Requirements for solder wires for soldering robots
Robots can be selected according to the needs of
barrels or disc welding wire. In order to reduce the frequency of replacement
of the wire, the robot should use barrels of wire, but the use of barrels of
wire, wire feeding hose is very long, large resistance to the welding wire
stiffness and other high quality requirements. When using less copper wire
quality, the copper surface due to friction off the friction tube will result
in reduced volume, high-speed wire feeding resistance increases, the wire can
not be sent out smoothly, resulting in jitter, arc instability, affecting the
welding Seam quality. Severe, there stuck phenomenon, so that the robot shut
down, it is necessary to promptly clean up the wire tube.
Summary of programming skills
(1) Select a reasonable welding sequence. To reduce
the welding deformation, welding torch walking path length to develop the
welding sequence.
(2) welding gun space transition requires a shorter
trajectory, smooth, safe.
(3) optimization of welding parameters. In order to
obtain the best welding parameters, the production of test pieces for welding
test and process assessment.
(4) a reasonable location of the positioner, torch
attitude, relative position of welding torch. After the workpiece is fixed on
the positioner, if the weld is not the ideal position and angle, it is required
to adjust the positioner constantly during the programming so that the welding
seam will reach the horizontal position one by one according to the welding sequence.
At the same time, , Reasonably determine the location of welding torch relative
to the joint, the angle and the wire out length. After determining the position
of the workpiece, the position of the relative position of the torch through
the programmer's eyes to observe, more difficult. This requires programmers to
sum up accumulated experience.
(5) the timely insertion of clean gun program. After a
certain length of welding program is prepared, the program should be inserted
in time to prevent the welding spatter jamming the welding nozzle and the
contact tip, to ensure the cleaning of the welding torch, to improve the life
of the nozzle, to ensure reliable arc and reduce welding spatter.
(6) the preparation process is generally not one step,
in the robot welding process to continuously test and modify the program,
adjust the welding parameters and torch attitude, etc., will form a good
program.
